Polaris RZR Engine Teardown | Part 4 in Series | Partzilla.com 

fantastic video and production! I don't even own one of these, just love tear downs and root causing problems, which is what you did!

Why doesn't anyone show taking the timing chain out? Of a 1000 XP.

Good Video, the plug had no gap because the rod bearing failed and caused the piston to travel up too high

Very professional. Well done.

Fantastic vídeo

Very well done video

I got a kick out of John being passive aggressive

Excellent video!

Engine blocks are actually very intuitive.....Carburetors are a different animal...but if you study them very close...you can find the problem...

Can you replace the jug and pistons while motor is still in the machine. I see the top end kits with pistons. I am getting blow bye and have low compression in one cylinder.

Hi partzilla ! I have a 2003 kawasaki bayou 250 any videos on engine work or electric problems ?

VERY informative!!!

Good video

Is it possible to remove the timing chain without splitting cases? Also what is the purpose of the U shaped retainer other than keeping the chain in place if dropped from the top?

thanks john, do you have video on changing a razor 900 jug'

Anyone know how to get the timing chain off the crank gear on the bottom behind the flywheel? Do you need a puller, or do you have to split the case?

instead of replacing the head wouldn't it be easier to put a thicker head gasket? Then it would put down the compression and give more room for the piston don't hit the spark plug? This coming from auto tech, those engines might not be possible to do.

How much different would this rebuild be on a 2013 Ranger 900xp?

do you have to pull motor to change jug on razor 900

dam you good!!!!!

Hi there could you tell me where can i find. Any piece of de engine. I need to repair one. But i dont found the piece??

can anyone tell me how to fix a airlock promblem for a polaris sport 400 coolent system?

Where is the number engine?

7:06 You called out main bearings even after seeing the smashed ground electrode on the spark plug...caused by the extra stroke by wasted rod bearings. Come on man this is first day stuff....lol Just joking btw, great video.

are you continuing with the engine rebuild videos?

Isn't that a manufacturer defect?

The coloration of the oil on the lobes had me cringe 😮

terminator eye

any one hello?
